Summary: | The invention relates to a special antenna for cable running state inspection equipment, which comprises a non-metal shell, a magnetic shielding layer, a limiting spring and a plurality of antenna units, the magnetic shielding layer is arranged on the inner side of the non-metal shell, the antenna units are arranged on the inner side of the magnetic shielding layer, and the antenna units are uniformly distributed in the circumferential direction. And the limiting spring is arranged between the antenna unit and the non-metal shell. According to the invention, electromagnetic induction detection can be directly carried out on any cable on a construction site, the whole antenna is rotated during use, the three groups of matrix antennas measure power frequency magnetic field signals at any position around the cable, the signals are sent to a host through a signal line, and the operation state of the cable can be accurately judged.
